EP53A8xQI – 1 Amp, 5MHz DC-DC Buck Converter with Integrated Inductor
The Enpirion EP53A8xQI 1 Amp, 5MHz DC-DC Buck (Step-Down) Converter, with integrated inductor, represents a revolution in the area of low-power switching converters. The total solution footprint is as small as 21mm2, without compromising efficiency.
A complete power system-on-a-chip (PowerSoC), the EP53A8xQI integrates power switches, inductor, gate drive, controller, and compensation in a tiny 3mm x 3mm package. The 1.1 mm profile and small footprint, enables the use of this part where space is at a premium. In addition, the Enpirion point-of-load solution requires only two tiny MLCC capacitors, reducing the overall solution cost and simplifying the supply chain.
The EP53A8xQI utilizes a 3-pin VID output voltage selector that allows the designer to choose one of seven pre-defined output voltage levels, or an external voltage divider can be employed to set the output voltage.
This power management IC is an excellent choice for low-power applications that require a small solution footprint, high efficiency, exceptional thermal performance, low noise, high reliability and ease of use.
